How to loop through all enum values in C#?

Yes you can use the ‍GetValue‍‍‍s method:

var values = Enum.GetValues(typeof(Foos));

Or the typed version:

var values = Enum.GetValues(typeof(Foos)).Cast<Foos>();

I long ago added a helper function to my private library for just such an occasion:

public static class EnumUtil {
    public static IEnumerable<T> GetValues<T>() {
        return Enum.GetValues(typeof(T)).Cast<T>();
    }
}

Usage:

var values = EnumUtil.GetValues<Foos>();

foreach(Foos foo in Enum.GetValues(typeof(Foos)))
